[sdnog] سؤال عن vlan

[Daniel Shaw]

Here's another example from a Cisco switch that does currently do L3 routing stuff, dual stack:

ar01.jnb#sh sdm prefer
The current template is "desktop IPv4 and IPv6 routing" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.

number of unicast mac addresses: 1.5K
number of IPv4 IGMP groups + multicast routes: 1K
number of IPv4 unicast routes: 2.75K
number of directly-connected IPv4 hosts: 1.5K
number of indirect IPv4 routes: 1.25K
number of IPv6 multicast groups: 1.125k
number of directly-connected IPv6 addresses: 1.5K
number of indirect IPv6 unicast routes: 1.25K
number of IPv4 policy based routing aces: 0.25K
number of IPv4/MAC qos aces: 0.5K
number of IPv4/MAC security aces: 0.5K
number of IPv6 policy based routing aces: 0.25K
number of IPv6 qos aces: 0.625k
number of IPv6 security aces: 0.5K

ar01.jnb#conf t
Enter configuration commands, one per line. End with CNTL/Z.
ar01.jnb(config)#sd
ar01.jnb(config)#sdm pre
ar01.jnb(config)#sdm prefer ?
access Access bias
default Default bias
dual-ipv4-and-ipv6 Support both IPv4 and IPv6
routing Unicast bias
vlan VLAN bias


I'll also just note that the device does have more than 8 routed SVI interfaces running. That is not a hard limit. But it does mean I have accepted that it's not optimised for both the number of vlan interfaces I have as well as the numbers above. But as I know that the numbers of routes and directly connected addresses is lower I should be ok.

depending on the switch that you buy, and what the code is licenced to
do, you can change this to different features (incl IPv6).
you can get more details using: “show sdm prefer”; you should see
something like:
sw02.6rdg#sh sdm prefer
The current template is "default" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.

number of unicast mac addresses: 4K
number of IPv4 IGMP groups + multicast routes: 0.25K
number of IPv4 unicast routes: 0.875k
number of directly-connected IPv4 hosts: 0.875k
number of indirect IPv4 routes: 0
number of IPv6 multicast groups: 0.25K
number of IPv6 unicast routes: 0.25K
number of directly-connected IPv6 addresses: 0.25K
number of indirect IPv6 unicast routes: 0
number of IPv4 policy based routing aces: 0
number of IPv4/MAC qos aces: 0.375k
number of IPv4/MAC security aces: 0.375k
number of IPv6 policy based routing aces: 0
number of IPv6 qos aces: 60
number of IPv6 security aces: 0.125k

you can see that “default” says that this is in the default state.
so i only have eight (8) routed vlans.
my switch is licenced for switching only (i don’t use it to route) so
i can’t show you more detailed stuff :-(
